As you have seen from the other responses, there are advantages to this 
(and carriers support it) in other parts of the world.  In the USA there 
isn't much need for such a device since calls to cell phones and calls 
to landlines cost the same amount.  In other parts of the world a call 
to a cell phone is MUCH more expensive that calls to a landline.

In many parts of Europe if you have a GSM gateway then the cell phones 
can become part of your Centrex system.
